Read the passage below carefully and choose the correct answer a, b, c, or d.
Paper is named for papyrus, a reed-like plant used by ancient Egyptians as writing material more than 5,000 years ago. The Chinese invented the paper that we use 2,000 years ago.
A piece of paper is made up of tiny fibers, not unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resins may add weight and texture.
Where do these fibers come from? The majority of paper is made from plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may be also made from things like old rags, or pieces of cloth. Wastepaper can be turned into recycled paper. This recycling process saves forests and energy and reduces air and water pollution.
